Application tiled December 2,1905. Serial No. 290,013-

fthe gear oi a self propelled vehicle driven by an electric motor.

It consists in fixing one of the supports to which the motor is attachedup on an eccentric sleeve in which the axle rotates in such a manner asto permit of altering the distance of the drive axle from the axis ofthedriving pinion in order to allow of the employment of pinions ofdifferent diameters.

The annexed drawing illustrates one method of carrying out-thisinvention.

The motor l, which drives the toothed wheel 2, is xed t0 the road wheel3 and is carried by two supports, one of which 4 encircles a sleeve 5which is mounted eccentrically on the axle 6, upon which it can turn.vUpon theangular position of the sleeve 5 in the support 4 depends thedistance apart of the centers o the toothed wheel 2 and the shaitvoi themotor. By altering this angular position the toothed wheel 2 may bedriven by -pinions oi different sizes and thus gearings of any sortsuitable to dierences in weight of the vehicle or in the nature of theroad.

The drawing illustrates in full and dotted lines the positions o themotor corresponding to the employment alternatively o two pinions 7 and8.

The sleeve 5 is maintained in the required position in the frame 4 byany suitable mechanical arrangement, for example by means oi a bolt 9vwhich may act both by tightening the frame and as a key bearing againstsuitable surfaces formed upon the sleeve 5. By removing the bolt theeccentric sleeve may be turned to the angle corresponding to 'thegearing desired.

Having now particularly described and ascertained the nature of myinvention and in what manner the same is to be performed, I declare thatwhat I claim is:

1. The combination of a drive-wheel, motor driven gears of diversediameter arranged to gear alternatively with the drive-wheel, and a gearsupport mounted eccentrically of the drive-wheel with a range ofdisplacement corresponding to the difference in size of the gears.

2. The combination of a drive-wheel, motor driven gears 'of diversediameter arranged to gear alternatively with the drive-wheel, a supportfor the gears having an eccentric bearing upon the axle of thedrive-wheel with a range of displacement corresponding to the diierencein the size of the gears.

3. The combination of a drive-wheel, motor driven gears of diversediameter arranged to gear alternatively with the drive-wheel, a supportfor the gears, an eccentric sleeve upon the axle of the Adrive-wheelserving as a hearing for the motor support and having a range ofdisplacement corresponding to the extreme difference in size of thegears.

4. In a motor vehicle, the combination of a drive-wheel,

an eccentric sleeve mounted on the drive-wheel axle, motor driven gearsof diverse diameter arranged to gear alternatively with thedrive-wheelfa gear support mounted on the eccentric sleeve, and meansfor shifting the position ot the sleeve relative to the support and axleto bring the gears alternatively Vintoroperative relation to thedrivewheel.-

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
